Botrytis, Frost and Pollination

Tuesday, June 9, 2015

We had some cool damp weather last week, up to and including Saturday.  Before this period, botrytis risk was low, but as we approach full bloom and with periodic wet periods approaching, protecting against Botrytis could be important.  (particularly if you have had a history of it in your fields).  Check the Wild Blueberry Pest Management Guide for allowable products ( WBB Pest Management Guide)

Remember if you have to spray, avoid contact with pollinators by spraying when it is cool or in the evening.  It's always a good idea to check with your beekeeper as well.

We had some light to moderate frost on Sunday and Monday mornings.  I haven't seen or heard of any damage.  The duration of the frost was generally short and temperatures did not appear to get low enough to cause any significant damage.
